According to the hadiths (Sayings of Mohammed) collected by Sahih Muslim (one of the three most authoritative collections in Islam), Mohammed forbade anyone from going to the mosque if they had eaten garlic. (Also see this article on a recent fatwa by a Kuwaiti cleric.)
Then there was that incident back in Italy back 2003, when the Italian Muslim convert Adel Smith became so enraged at the crucifix on the mantle of his 70-year-old mother's room at a Catholic hospital (the San Salvatore hospital in Aquila), that he literally threw the crucifix out the window.
These make one wonder if there is some... let us say, consanguinity between Muslims and vampires.
Perhaps also of relevance in this regard, cited from the Wikipedia entry on "vampires" is an interesting detail from the book Vampires, Burial and Death: Folklore and Reality by Barber, Paul (1988):
Other methods [of warding off vampires from graveyards] commonly practised in Europe included... placing poppy seeds, millet or sand on the ground at the grave site of a presumed vampire; this was intended to keep the vampire occupied all night by counting the fallen grains...
And it may be apposite, if not ironic, in this regard to note that the original Dracula himself, Vlad the Impaler, was, in his capacity as a defender of the eastern West from Muslim invaders, perhaps more of a vampire hunter than a vampire per se himself.
